Struct RandStrBuilder

pub struct RandStrBuilder { /* private fields */ }

Builder for generating random strings.

Implementations

impl RandStrBuilder

pub fn upper(&mut self) -> &mut Self

Allows the generator to produce uppercase letters.

pub fn lower(&mut self) -> &mut Self

Allows the generator to produce lowercase letters.

pub fn letter(&mut self) -> &mut Self

Allows the product to produce uppercase and lowercase letters.

pub fn whitespace(&mut self) -> &mut Self

Allows the generator to produce whitespaces.

pub fn digit(&mut self) -> &mut Self

Allows the generator to produce digits.

pub fn symbol(&mut self) -> &mut Self

Allows the generator to produce symbols.

pub fn custom(&mut self, custom: &str) -> &mut Self

Allows the generator to produce custom characters.

pub fn all(&mut self) -> &mut Self

Allows the generator to produce all characters.

pub fn must_upper(&mut self) -> &mut Self

Forces the generator to produce strings containing uppercase letters.

pub fn must_lower(&mut self) -> &mut Self

Forces the generator to produce strings containing lowercase letters.

pub fn must_letter(&mut self) -> &mut Self

Forces the generator to produce strings containing letters.

pub fn must_digit(&mut self) -> &mut Self

Forces the generator to produce strings containing digits.

pub fn must_symbol(&mut self) -> &mut Self

Forces the generator to produce strings containing symbols.

pub fn must_whitespace(&mut self) -> &mut Self

Forces the generator to produce strings containing whitespaces.

pub fn must_custom(&mut self, custom: &str) -> &mut Self

Forces the generator to produce strings containing custom characters.

pub fn rng(&mut self, rng: ThreadRng) -> &mut Self

Sets the random number generator to use.

pub fn len(&mut self, len: usize) -> &mut Self

Sets the length of the generated string.

pub fn build(&self) -> RandStr
